Abstract
A first parity calculator calculates one parity bit for serial binary data to be subjected to a conversion process. A second parity calculator calculates one parity bit for serial binary data obtained as a result of the conversion process. When both parity bits do not match, a multiplexer outputs, as a parity bit of the serial binary data obtained as a result of the conversion process, a parity bit obtained by inverting one parity bit included in the serial binary data to be subjected to the conversion process.
Claims9
A data conversion apparatus comprising:
- a converter configured to convert one or more bit values of first serial binary data and a parity bit P1 added to the first serial binary data, in accordance with a predetermined conversion rule into corresponding one or more bit values of second serial binary data and a parity bit P2 added to the second serial binary data, the conversion including, for each of the one or more bit values of the first serial binary data, selectively:
- inverting the bit value,
- non-inverting the bit value,
- converting the bit value into 0, or
- converting the bit value into 1;
- a first parity calculator configured to calculate a first parity bit PB1 for the first serial binary data;
- and
- a second parity calculator configured to calculate a second parity bit PB2 for the second serial binary data, wherein:
- when the first parity bit PB1 and the second parity bit PB2 match, the converter is configured to output the parity bit P2 by non-inverting the parity bit P1, and
- when the first parity bit PB1 and the second parity PB2 bit do not match, the converter is configured to output the parity bit P2 by inverting the parity bit P1.
